Application filed March 1-51, 191

To all whom it may concern:

Be it known that I, NICOLA PAPA, citizen of the United States, residing at Utica, in the county of Oneida and State of New York, have invented new and useful linprovements in Electric-Light Apparatus, of which the following is a specification.

This invention is an improved electric light apparatus adapted for use light and also adapted for use as light, as hereinafterdescribed and I The object of the invention is to provitl an electric light and means to cause th same to project either a steady beam or to project a series of twinkling or rapi liy successive beams which have a biinding efl'ect on persons in front of the light, and so that the apparatus may be used either as an ordinary search light or as a blinding light in time of war.

The invention consists in the features of construction, combination, and arrangement of devices, hereinafter described and claimed.

In the accompanying drawings:

Figure 1 is a sectional View of an electric light apparatus constructed in accordance with my invention.

Fig. 2 is a detail elevation of the twin kling or intermittently acting switch.

Fig. 3 is a diagram in which the electric circuits are traced.

Fig. at is a sectional view of a modified form of the electric light apparatus in a manually operated intermittently actii'zg switch is employed.

In the embodiment of the invention shown, a suitable casing 1 is provided in the front end of which is a lens 2. reflector 3 is arranged in the casing, in rear of the lens and a cluster 0t electric lamps 4: are arranged in the center of the reflector. Conductors 5, 6, are connected to the electri lamps and to a source of electricity conventionally indicated. at? in Fig. 3 ductor 6 is provided with switch 8, which I will here term a constant switch, and which when closed causes the electric is to be supplied with current and to a steady light which enables the a to he used as a search light.

ll also provide an intermittentiy switch 9 which is here shown as c a revoluble conducting member 10 three radially arranged cendnctin 11. The intermittentli actnw s incindes pair of spaced fixed contact points,'l2, 153 which are here shown secured and insulated from a supporting arch bracket 13, the inisaiation of said fixed contact points heing ii heated at i l. The point 122 is connected a conducting wire to the condu tor 6 o circuit, and said spaced contact points i motor is connected by conductor i8 conductor 5 and by ccndaetcr 19 to n e t dnetor i5, aid conductor it being i ided with cent-act points 20. The is n'icnnted on and from the shaft 521 of the motor, the insulation being indicated at 22 in Fig. 2. A double knife switch 23 is provided, one member 2% of which is adapted ts compiete circuit hetwee' the points 16, the member 25 of said switch being adapted to complete a circuit through the points 1 e ectric light 15 includes Eihen the switch 8 opened, and the switch is clo .d the intermittently ac o ether with the eiect' cluded in ninltiple z the moto the men nit, hence .eniber F9 its close by contacting with. and

points- 12, 12, so the t of i hence prevent the from being visunng en'ec locality of appa ally distinguished.

atus

'ience the apparatus is adapted to he used er as a search tight or as a blinding at wiil.

is shown i n l and socket oinhie switch. element 10 i lights are indicated at e, the battery at 7 and the constant switch at 8".

It is believed that, from the foregoing description, the nature and advantages of the invention will be readily apparent without requiring a more extended explanation and therefore the same has been omitted However, I desire to have it understood that Various changes in the construction and arrangement of parts may be resorted to when desired as fall within the scope of the appended claim.

Haring described the invention, what is claimed is:

An apparatus of the class described, a circuit includinga light and a switch, a shunt of said circuit including an electric motor, a subshunt excluding the motor and including a motor driven intermittentl acting switch, and switches to open and close the shunt and subshunts, whereby when the first named switch is closed and the last named switches are open, the light will operate continuously, and when the first named switch is open and the last named switches are closed the lightwill llash intermittently.

In testimony \\'liereot', l allix my signature in presence of witnesses.
